In this fully audited 16-creator, 136-post sample, PrepGo behaves less like a study app buying isolated reviews and more like a publisher staffing an AP-season media network. Eight accounts enter the unified `Ambassador` cohort: `cclaw35` mentioned PrepGo in 30 of 30 recent TikToks, `samristudys` in 28 of 30, `studywithtayy` in 12 of 16, `westudybuddies` in 11 of 12 recent Instagram posts, and the newly traced `liliesnotebook` in 12 of 12.
That feed label does not guess a contract: bios that merely name or link PrepGo remain context, while TikTok posts from `evalins.studies`, `samristudys`, and `studytipswdrea` separately prove paid relationships through `#ad`, `#sponsored`, or `#advertisement`.
Across 104 TikToks and 32 Instagram Reels, the recurring system is to lead with useful AP-native advice—countdown rescue, grader rubrics, mistake diagnosis, or student-life anxiety—then make PrepGo the practice layer. The strongest observed posts were the advice, not the sales pitch: a DBQ breakdown reached 2.1M views and a one-day AP rescue plan reached 1.7M.
Every retained post now has a complete transcript and ordered-frame review; this remains a sampled view, not a census.
